Just in case you were wondering, if a Colombian drug lord kills your hitman father and the rest of your family, seeking revenge by becoming a Latina-ninja serial killer who only kills “bad” people won’t heal the hole in your heart. Just in case you were wondering. Being a spectator to such methodically planned out carnage can be quite interesting, however. “Colombiana” (2011) is an inexplicably over-the-top, exciting, dark, oddly satisfying examination in payback. It’s like “Man on Fire” and “Dexter” had a sloppy one-night stand and then either “Dexter” or “Man on Fire” took drugs while they were pregnant.
